Overall Rating
Alpina B5:
The Alpina B5 and D5 are a series of high performance executive cars manufactured by German Automobile manufacturer Alpina. Introduced at the 2017 Geneva Motor Show, the car is the third generation of the B5 and succeeds the Alpina B5. Based on the BMW 5 Series , the car is available in both saloon and wagon bodystyles.

Modifications include a re-designed air intake, cooling system, higher compression Mahle pistons, twin-scroll Garrett turbos, a larger intercooler, new NGK spark plugs and revised ECU map.

The transmission allows 100 launches before disabling the feature to preserve reliability....(Read more on Wikipedia)
